Raindrop energy harvesting is a rubbish idea. The raindrops simply don't have a meaningful amount of energy to begin with: https://news.ycombinator.com/item?id=36907674
I mean, not in the sense that they're trying to do it, but that's ultimately what drives hydroelectric dams.
Sure, but those are completely different approaches. Dams have the advantage that they have a much larger capture area for water and that they can accelerate the water beyond the 10 m/s terminal velocity of raindrops.
We gotta build a reservoir just below cloud level and then put turbines all the way down to sea level to harvest more of the energy
Blimp reservoirs!
